[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ear tag for animals to be attached to the ears of livestock such as pigs, cows, sheep, and forceps used to attach the ear tags to the target animal.

[0002]

2. Description of the Related Art Livestock such as pigs, cows, and sheep are vaccinated at a certain time after birth for the purpose of preventing the transmission of an infectious disease. It is customary for each owner to wear a marking to identify when they have been vaccinated. Conventionally, this kind of animal ear tag is mounted while piercing the ear with forceps, but the details of the structure are described in the tip of the column part standing from the disc-shaped ear backing plate, And a body for drilling, which has a cone-shaped drilling execution portion having a large tip and a sharp tip, and a hook in which the above-mentioned pillar portion is loosely fitted and the hole edge is hooked on the step portion between the pillar portion and the drilling execution portion. It has a stop hole and is composed of an identification display tag that holds the ear of the animal in a non-removable manner with the ear backing body, and the body for perforation and the identification display tag are scissor-shaped forceps. The forceps are detachably attached, and the forceps are closed and attached while the ears are positioned between them (see, for example, JP-A-58-179421).

[0003]

However, in the conventional animal ear tag, the perforation executing portion at the tip thereof is integrally formed with the perforation body by insert molding. That is, the perforation execution part is made of a conical sharp metal material to ensure the perforation. Therefore, when the operator grasps the ear and moves the animal to the injection or the target place, the piercing part of the attached ear tag may injure the finger, or the color of the identification tag etc. When the domestic animals bite each other's ears and make instinctive behaviors that interfere with each other and interfere with each other, the domestic animals may get injured in their mouths and tongues at the piercing execution part, which is a problem. There is. In order to avoid the problem, some identification tags have a cylindrical portion that covers the piercing execution part, but the length (height) of the pillar of the piercing body is the same as that of livestock (cattle, pig, Since it is standardized regardless of the sheep, etc., the identification indicator tag moves toward the ear backing body depending on the ear thickness to be grasped, the punching execution part protrudes from the cylinder part, and the operator's finger It may not be a fundamental solution because it may cause injuries by hitting the tongue and tongue of livestock.

The present invention has been made in view of the conventional circumstances, and does not cause injury even if the ears are gripped when the livestock after being mounted are forcibly moved to a desired place, and the livestock are not ears. An object is to provide an animal ear tag that is safe even if a behavior of nipping the ear tags attached to the animal is performed, and forceps used to attach the ear tag.

[0005]

[Means for Solving the Problems] The technical means taken to achieve the above-mentioned object is, in claim 1, that the hole-performing part of the body for perforating is integrally formed with the pillar part and the locking hole of the identification indicating tag. It is composed of a large frusto-conical portion that locks to the edge and a sharp body for ear piercing that is continuously provided flush with the tip of the large portion without any steps. So that it has a conical shape, and further, a communication hole is opened by communicating with the ear backing plate, the column portion and the large portion, and the sharp body for ear punching can be separated at the tip of the communication hole. The gist is that it was fitted in.
According to a second aspect of the present invention, there is provided an ear backing plate and a pillar portion, each of which has a large portion integrated with a tip end of the pillar portion standing from the ear backing plate, and a sharp body for ear perforation provided at the tip of the large portion. A body for perforation in which the above-mentioned sharp body is detachably fitted to the tip of a communication hole communicating with the large-sized portion, and locking for locking the pillar portion at a step portion between the large-sized portion and the pillar portion by loosely inserting the pillar portion. A forceps for attaching an animal ear tag consisting of an identification display tag having a hole to the ear of the target animal, which is formed into a bifurcated shape at the tip of the forceps body that can be opened and closed in a scissor shape. A supporting portion projectingly fitted to the base end of the communication hole of the punching body is projectingly provided at one end of the pinching mouth portion, and an identification display tag is sandwiched between the other end and the other end and a sharpened body. Of the punching body, the sharpening body of the punching body, the inserting portion of the sandwiching body, and the through hole facing the locking hole of the identification display tag. A pusher that has been opened and is pierced through the support portion so as to be reciprocally movable in the communication hole, and at the end of closing the nipping mouth portion, the pusher is moved forward in conjunction with the closing movement of the forceps body to move the tip of the body for punching. The gist is that a transmission means for forcibly pushing out the sharp body is provided.

[0006]

According to the above technical means, the following actions are achieved. (Claim 1) Only the large-sized portion forming the stepped portion for locking with the locking hole with the column is forcibly extruded by forcibly pushing out the sharpened body with the rod or the like entering from the communication hole. Exposed to outside. The sharp body detachably attached to the tip of the large-sized portion is continuously provided flush with the tip of the large-sized portion without a step, and is joined and integrated to form a conical shape. When the ear portion is pierced, the animal's hair or skin does not enter between the joint surfaces of the large portion and the sharp body, and the smooth piercing is possible. (Claim 2) The ear of the animal interposed between the body for perforation and the identification display tag, which are supported or clamped so as to face one end and the other end of the forceps body, is perforated with a sharp body. When the closing of the pinch portion is completed, the pusher is moved forward by the interlocking transmission means to push out the sharpened body fitted to the tip of the communication hole and separate it from the body for drilling.

[0007]

Since the present invention is constructed as described above, it has the following advantages. (Claim 1) Since the sharp body for ear perforation is separated from the large-sized portion and the large-sized portion only protrudes from the identification display tag, the object is to be locked in the locking hole of the identification display tag. It is not necessary to form a large-sized portion for holding the animal's ear into a sharp perforated shape, and the external shape can be formed into an arbitrary shape such as a smooth outer shape. Therefore, even if the large-sized part only projects from the identification tag, the operator who holds the ear when moving the livestock does not get injured fingers or hands, and even if the livestock bites the animal with interest in the identification tag Safety can be imparted to both workers and livestock without injury to the mouth or tongue.

Moreover, since the sharp body at the tip is pushed out by the rod or the like which enters from the communication hole, a step for catching a tool for removing the sharp body is formed between the sharp body and the large-sized portion. No need. Therefore, there is no possibility that the sharp body falls off and is lost before something is caught on the caught step and punched.

Further, since it is not necessary to form the cover of the large-sized portion on the identification tag, it is possible to contribute to the reduction of the molding cost of the identification tag and the material cost, and consequently the unit price of the animal ear tag itself. Can be expected.

(Claim 2) It is convenient that the animal ear tag according to the above-mentioned claim 1 can be securely attached to the ear of the target animal, and the sharp body for ear perforation can be automatically separated at the tip. Forceps can be provided.

Unlike the identification display tag 1 having the same structure as the conventional one, the punching body 2 has a new structure. As in the conventional case, the identification display tag 1 has a surface portion 1b on which symbols and characters necessary for identification are provided.
The arm piece 1c is formed integrally with the arm piece 1c, and the engaging hole 1a is formed in the arm piece 1c, and is integrally formed of a synthetic resin material having some elasticity.

The perforation body 2 is a disc-shaped ear backing body 2a.
And a column portion 2b of a desired height standing upright from the center of the ear backing body 2a, and a perforation execution portion 2c formed at the tip of the column portion 2b. The perforation execution portion 2c is the column portion. It is composed of a large portion 2c 'which is slightly larger than 2b and a sharp body 2c "for ear perforation.

The perforating body 2 is integrally formed by using a synthetic resin material except for the sharp body 2c "for perforating the ear at the tip, and the ear backing body 2a, the pillar portion 2b, and the large portion 2c '. A communication hole 2d is opened over the area.

The height of the pillar portion 2b is uniform. Specifically, regardless of livestock (pigs, cattle, sheep, etc.), 1.5 to 2c
It is about m.

As shown in FIG. 2, the large-sized portion 2c 'is formed in a substantially trapezoidal shape, and the pillar portion 2b has a diameter of 3 to 4 mm, while the lower edge has a diameter of about 5 mm. .

The sharp body 2c "for ear piercing is made of the same synthetic resin material as the ear backing body 2a and the pillar portion 2b, and is formed into a pointed shape. Specifically, it is a conical shape with the large portion 2c '. It is formed to have an outer surface shape that reveals the shape, and a fitting protrusion 2c ″ ′ is formed protruding from the lower surface thereof so as to be fitted to the tip of the communication hole 2d and separable from the large portion 2c ′. ing.

The diameter of the locking hole 1a is equal to that of the boring body 2.
The column portion 2b of c ″ is loosely fitted, that is, about 3.5 mm to 4.5 mm.

Next, the simple operation of this embodiment will be described. First, using the conventional forceps (not shown), the body 2 for perforation is first prepared.
And the identification tag 1 are attached to one end and the other end of the forceps (not shown), which form a gripping opening (not shown). In that state, the ears (not shown) of the animal to be perforated are positioned between them, and the forceps (not shown) are closed to close the pinching mouth. At that time, the sharp body 2 of the body 2 for perforation
c "and the locking hole 1a are in a direct relationship, and the identification tag 1

The sharp body 2c ″ that advances while piercing the ear 100 and further expanding the locking hole 1a is the large portion 2
When the stepped portion 2h between the c'and the pillar portion 2b projects from the locking hole 1a, the stepped portion 2h faces the through hole. Then, a rod member is inserted through the linear hole (not shown), and the fitting protrusion 2c ″ ′ is pushed by the tip to remove the sharpened body 2c ″. After that, the ear 100 and the ear may be removed from the forceps (not shown). In addition, after removing from the forceps (not shown), the communication hole 2d
A sharp tool 2c ″ at the tip may be pushed out by inserting a rod-shaped tool from the above. As a result, only the large-sized portion 2c ′ is exposed from the identification display tag 1 and the animal ear tag A is attached to the ear. It is not necessary that the sharp body 2c "and the large-shaped portion 2c 'be exposed exactly as a conical shape, and the sharp-shaped body 2c" is formed in a slightly small size so as not to be caught between the large-shaped portion 2c' and the large-shaped portion 2c '. Even if it exists, it is optional. Since the sharp body 2c ″ can be separated, it is of course optional to form it with a metal material in order to improve the piercing force.
